Leaders in IHC Validated Antibodies

We have a collection of 421,628 monoclonal and polyclonal antibodies to most target proteins. They cover all major research species, applications, and are available in multiple conjugated forms. Our IHC-plus™ antibodies are highly characterized for use in FFPE human tissue Immunohistochemistry.

Our traditional Sandwich, Competitive EIA, and Direct ELISA kits provide a means to quantitatively measure thousands of targets of interest, while our Cell-Based and DNA-Binding ELISA kits are ideal for in-vitro studies and transcription factor analysis. 

Our growing collection of Assay kits provide researchers with the tools to monitor a variety of biological processes, such as apoptosis, cell proliferation, metabolism, and more in a variety of formats. Each kit includes all of the necessary reagents to conduct the assay, and a clear, detailed protocol.

Proteins can be used in a wide variety of applications, such as for the development of functional assays, small-molecule screening, receptor activation in-situ, or simply as controls for a Western Blot. We offer extracted native proteins and recombinant proteins in the form of cell lysates, or purified from bacterial or mammalian expression systems. Many proteins are bio-active and certified low-endotoxin.
